SPECIFICATION forming part of Letters Patent No. 295,135, dated March11, 1884. Application filed August 9, 1883. (No model.)

To ctZZ whom it may concern.-

Be itknown that we, THOMAS "WILLInMs, ALFRED Manon, and HENRY A.WILLIAiIs, citizens of the United States, residing at Princeton, in thecounty of Gibson and State of In diaua, have invented certain new anduseful Improvements in Elevators, of which the following is aspecification, reference being had therein to the accompanying drawings.

The object of our improvement is to obtain a portable elevator of simpleconstruction for raising and stacking hay and straw especially, butadapted to moving and loading general matter, the machine to be workedby steam or other suitable means. This object we attain by meansillustrated in the accompanying drawings, in which-- Figure l is avertical sectional view of our invention,with the upper part of theinclined way and one side of the machine broken elf in order to betterillustrate the automatic operation of the dumping-racks for handling andfor shifting the load. Fig. Zis a bottom view of the upper part of theinclined way with the ascending dumping-rack in dumping position. Fig. 3is a front elevation with the upper part of the inclined way broken off.4 is a vertical sectional view through the upper part of the inclinedway, with the dumping-rack in the same position as shown in Fig. 2. Fig.5 is a detached sectional view of the pulleys located at the upper partof the inclined way, and Fig. 6 represents a longitudinal sectional viewof the upper part of the elevator.

The letter A indicates the frame of the elevator, which, for the purposeof being moved from place to place, is mounted upon suit-abletruck-wheels, B.

D indicates two beams, which are secured to the elevator-frame at anangle of forty-five degrees, or thereabout, by means of bolts, whichbeams are designed for and act as an inclined way for supporting andguiding the ascending dumping rack. These inclined beanisheve grooves onthcir'inner sides. (Indicated by the letter 3.) Between the upper partof the inclined way and the base of the elevator-frame are twostanchions, G, for strengthening the same.

E indicates the driving-pulley, connected by abelt, F, with a plainpulley, G, attached to which is a grooved pulley, H, as shown in Fig. 3,for receiving and working the knotted or balled wire, rope, or chain 1,which connects uvith a grooved pulley, N, secured on the shaft U at theupper part of the inclined way, as seen in Fig. 2. site the pulley E(seen in Fig. 1) is another driving-pulley, 1). (Shown in Fig. 3.) lhispulley b connects'by a crossed belt, J, with a pulley, K, for operatingin an opposite direction to the knotted or balled wire, rope, or chainI, another knotted or bailed wire, rope, or chain, L, connecting with aloose grooved pulley, M, on a shaft at the upper part of the inclinedway, as especially shown in Figs. 2 and 4. This grooved pulley Mis madeto work loose on the shaft mentioned, in order that it On the same shaftwith but oppomay move in an opposite direction to the pulley N on thesame shaft. O are the knots or balls secured on the ropes or chains Iand L, only one being used-on the rope or chain I and five or more onthe rope L. These knots or balls are for the purpose of catching inslots in pawls at different times. which pawls are pivoted to adumping-rack, V, as will be more fully hereinafter described.

Operating in connection with the rope or chain I is a slotted arm, P,Fig. 1, projecting from the shaft Q, pendent from which is a weight, R,for throwing the arm P back to its normal position, from which it isperiodically moved by the knot on the chain or rope I.

Attached to the frame A are projecting beams d, to which is secured acheck-rack, S. The letter Tindicates a dumping-rack mounted on a shaft,T, journaled in hearings in the frame A. The check-rack is for thepurpose of preventing the hay from falling oft the front of thedumping-rack when it is pitched there from awagon or stack, to beelevated to a higher position.

The dumping-rack is connected bymeans of the rod U with the projecting;rod l? on the shaft Q, and thus, when the knot or ball on the rope orchain 1 engages the slot in the arm P on the same shaft and tilts itforward, it discharges the dumping-rack above mentioned.

Resting and moving upon the inclined way is a dumping-rack, V, with anapron, hand slotted pawls X, one of which is engaged by the rope I andthe other by the rope L, these pawls fitting over the knotted ropes orchains i and being held and returned to their normal position by meansof springs X.

Attached to the inclined wayby a pivot at the upper part of andunderneath thev same is a transverse bar, Y, Fig. 2, carrying an uprightprojection, Y, Fig. 6, reaching to the dumping-rack V, for starting thelatter upon its return course after'its load has been dis charged, bybeing operated by the knot on the rope L'engaging the arm a, whichoperates the bar Z, connected to the transverse bar Y,thereby operatingthe upright Y. The bar Y is supported in position by and works within anarbor lettered c, it also being connected by means of a rod, Z, to aslotted arm, a, projecting from the side of the inclined way,which isoperated by the knotted or balled rope I,thus operating the transversebar Y. The ascending dumping-rack V isaffixcd to and held in position bycross-heads h h, working in the grooves g of the inclined ways D. (Shownin Fig. 4.)

By. putting the machine in motion the knotted or balledropes or chainswill travel in opposite directions by reason of the twisted belt J, thuscausing the knot on the rope or chain I to descend and catch the slottedarm P',which and dumping rackV.

will tip, causing the dumping-rack T to dis charge itsload on the apronNV of the sliding,

The ball or knot on the rope I, after passing the arm I passes aroundthe grooved pulleyH and engages a slotin the pawl, under which the ropeI passes on the rack V, carrying the rack upward with its load. Afterhaving reached the top of the inclined ways, the apron WV, on which isthe load, drops over the top, as shown plainly in Fig. 6 of thedrawings.

gaged far enough over the pulley N for it to pass under, and continuesdownward until it engages the slot in the arm a, which then operates thetransverse bar Y, causing the up- After this the knot or ball releasesitself by pushing the pawl with which itis enright Y, secured thereto,to push or start the rack V downward until it stops on a knot or ball onthe ropeL,which is moving downward, as indicated by the arrow in Fig. 6,and is then lowered gradually by this rope, which serves only to-permitthe rack to descend in uniformity with the other rope, I, instead ofdropping by its own gravity. The knots or balls on the rope or chain Lalso engage the slotted arm a on the under side, operating it in anopposite direction to the ball or knot on the rope I, thus placing theupright Y on the transverse bar Y in its normal position.

Having thus explained the construction and operation of our invention,what we claim,and desire to secure by Letters Patent, is-

1. In a portable elevator, the ascending dumping-rack V, provided withan apronJV, and cross-heads h h, in combination with the inclinedgrooved beams D, the knotted or balled wires, ropes, or chains, thepawlsXand their springs, the projecting slotted arm a, the transversebar Y, having an upright,Y, arbor c, and rod Z, substantially asdescribed.

2. In aportable elevator, the arm P, slotted arm P, and a weighted shaftQ, in combination with the knotted or balled wire, rope, or chain I, theconnecting-rod U, and the dumping-rack T, substantially as described.

3. In a portable elevator, the combination of the knotted or balledwires, ropes, or chains, the pulleys,-driving mechanism, the projectingslotted arms I? and a and their connections,

and the du m pin g-racks opera-ted thereby, sub- THOMAS WILLIAMS. ALFREDMAUGK. HENRY A. WILLIAMS.
